In the RM0456, the LPUART has a block diagram (67.4.1) with a register called LPUART_ RTOR but there is no documentation about this register. For USART, this register is related to Receiver timeout interrupt but this feature is not available for LPUART.

Hi @nicolas
I confirm Receiver Timeout feature is not supported on LPUART instance on U5, as stated in 67.3, making the RTOR register not relevant for LPUART.
Even if register might be present in peripheral, it cannot be used.
